SNOV MAGOUN, OF NEWTON, MASSACHUSETTS, ASSIGNORl TO MOORE 8v v CROSBY.

IMPROVED MACHINE FOR CUTTING AND BEVELING PRINTERS RULES.

Specification forming part of Letters Patent No. 9,964, dated August 21853.,

To all whom it may concern:

Be it known that I, SNOW MAGOUN, of Newton, in the county of Middlesexand State of Massachusetts, have invented a new and useful Machine forCutting and Beveling Printers Rules; and I do hereby declare that thefollowing description, taken in connection with the accompanyingdrawings hereinafter referred to, forms a full and exact specificationof the same, wherein I have set forth the nature and principles of mysaid invention by which it may be distinguished from others of a similarclass, together with such parts as I claim and desire to have secured tome by Letters Patent. v p

The iignres of the accompanying plate of drawings represent myimprovements.

Figure l is a plan or top view of my machine. Fig. 2 is a transversevertical section of the machine, taken in the plane of the line A B,Eig. l. Fig. 3 is a vertical section taken in the plane of the line C D,Fig. 1.

Printers rules-the strips of metal used by printers for rulinglines-have hitherto been cut oft' and beveledby a slow and tediousprocess by hand, the strip being usually cut off by a saw and the edgesafterward mitered or beveled by ling. By my improved machine they can befinished with much greater speed and nicety than by hand, being cut offand beveled by a tool set in a sliding carriage and operated as will behereinafter explained.

a a o. a in the drawings represent the bedpiece or bottom frame of themachine, to which are attached the standards b b, in which are thebearings for the sliding tool-carriagec cc.

In this carriage are placed the cutting-tools e and f, the. tool e beingused for cutting the rule off square and the tool j' for beveling therule.

. The strip of metal from which the rule is to be cutis placed upon thebed-piece a a, and rigidly held by the set-screws g g, and at the end bythe slides h h, fastened in any desired position by set-screws t' t'.The tool-carriage c c c is moved forward and back across the bed-piece aa by the handle k 7c, turning on a fulcrum at Z, and jointed to the armm, which is attached to the tool-carriage at n. The tools are depressed,as the cutting progresses, by the screws o o, and raised up again whenthe screws are relieved from the tools by the springs 1) p.

By the above-described arrangement it will be seen that the rule can becut to any desired length and also beveled to any desired angle bychanging the bevel of the tool accordingly, these results at the sametime being effected with much greater speed and nicety than by theordinary method of cutting printers rules.

Having thus described my improved machine for cutting printers rules, Ishall state my claim as follows:

The machine hereinabove described for cut.

ting and beveling printers rules, constructed with a slidingtool-carriage, which carries the cutting-tool forward and back acrossthe rule, as above set forth.
